IN WHAT WAY CAN ON-LINE WASHING IMPROVE EFFICIENCY?

On-line cleaning is not as efficient as off-line cleaning and eventually all gas turbines will require an off-line wash to restore power. The idea of on-line washing is to extend the period between off-line washes by regaining most of the power lost between on-line washes, thereby slowing down the degradation and extending the period between off-line washes. On-line washing should be carried out at a frequency that maintains the compressor as close to maximum efficiency as possible.
